How to convert grams to milliliters? 10 easy exercises

The conversion from grams to milliliters depends on the substance you are measuring, since the density of different substances varies. However, if you know the density of the substance in question, you can use the general conversion formula:

Milliliters (mL) = Grams (g) / Density (g/mL)

For example, if the density of the substance is 1 g/mL, simply divide the number of grams by 1 to get the equivalent in milliliters.

Suppose we have a liquid substance with a density of 0.8 g/ml and we want to convert 120 grams of this substance to milliliters. We can use the formula:

It is important to note that this formula is only applicable if the density of the substance is constant and known. In cases where the density varies, it is necessary to use specific conversion tables or information provided by reliable sources to make the accurate conversion.

Here are 10 simple grams to milliliters conversion examples that are suitable for elementary or middle school students:

1. Water: Under normal conditions, the density of water is approximately 1 gram per milliliter (you can see it in the table above). Therefore, if you have 50 grams of water, the conversion to milliliters, applying the formula, would be:

Milliliters (mL) = Grams (g) / Density (g/mL) Milliliters (mL) = 50 g / 1 g/mL Milliliters (mL) = 50 mL

Therefore, 50 grams of water equals 50 mL. Was it understood?

In case there are any doubts, let's go with another small exercise:

2. Flour: The density of the flour can vary, but on average it is estimated to be around 0.57 grams per milliliter. If you have 100 grams of flour, the conversion to milliliters would be:

Milliliters (mL) = Grams (g) / Density (g/mL) Milliliters (mL) = 100 g / 0.57 g/mL Milliliters (mL) ≈ 175.4 mL (approximately)

Therefore, 100 grams of flour is equivalent to approximately 175.4 mL.

Exercise 3: Convert 300 grams of milk to milliliters. Milk density: 1.03 g/mL Solution: Volume (mL) = Mass (g) / Density (g/mL) = 300 g / 1.03 g/mL ≈ 291.26 mL

Exercise 4: Convert 150 grams of olive oil to ml. Density of olive oil: 0.92 g/mL Solution: Volume (mL) = Mass (g) / Density (g/mL) = 150 g / 0.92 g/mL ≈ 163.04 mL

Exercise 5: Convert 250 grams of sugar to milliliters. Sugar density: 0.85 g/mL Solution: Volume (mL) = Mass (g) / Density (g/mL) = 250 g / 0.85 g/mL ≈ 294.12 mL

Exercise 6: Convert 180 grams of salt to milliliters. Density of salt: 2.16 g/mL Solution: Volume (mL) = Mass (g) / Density (g/mL) = 180 g / 2.16 g/mL ≈ 83.33 mL

Exercise 7: Convert 120 grams of ethyl alcohol to milliliters. Density of ethyl alcohol: 0.789 g/mL Solution: Volume (mL) = Mass (g) / Density (g/mL) = 120 g / 0.789 g/mL ≈ 152.28 mL

Exercise 8: Convert 350 grams of honey to milliliters. Density of honey: 1.42 g/mL Solution: Volume (mL) = Mass (g) / Density (g/mL) = 350 g / 1.42 g/mL ≈ 246.48 mL

Exercise 9: Convert 90 grams of sodium chloride (table salt) to milliliters. Sodium Chloride Density: 2.17 g/mL Solution: Volume (mL) = Mass (g) / Density (g/mL) = 90 g / 2.17 g/mL ≈ 41.52 mL

How to convert from milliliters to grams

The reverse conversion from (mL) to grams (g) depends on the density of the substance in question. Density is the relationship between the mass and volume of a substance. Since different substances have different densities, there is no single conversion formula. However, if you know the density of the substance, you can use the following formula:

Grams (g) = Milliliters (mL) x Density (g/mL)

For example, if the density of the substance is 0.8 g/mL and you have 100 mL of that substance, the conversion would be:

Grams (g) = 100 mL x 0.8 g/mL Grams (g) = 80 g

Remember that this formula is only applicable if you know the density of the substance in question. If you do not have density information, an accurate conversion is not possible.
